The Honourable Richard Rollison (aka 'The Toff') finds himself involved in a search for a lost relative – there is a large inheritance at stake. However, the aunt of the beautiful heiress is found murdered and the search for who might be prepared to go to such lengths in order to get their hands on the fortune leads to him and the heiress travelling all the way to Australia. There, the mystery deepens and there is clearly significant danger if the enquiry is pursued any further. An exciting finish to the hunt brings this adventure to a surprising finale.
